^^ as above. I used that in all of my courseworks.
As for writing notes - imo computers are pretty useless for writing up of important maths stuff.
LateX - it was designed for typing out and printing equations.

This. LaTeX for me was invaluable during my MSc, you should even do your coursework/thesis in it too![]()
IMO re-write them up by hand if you need to.
Will be A LOT quicker
